What are the biggest challenges facing adult common readers today?

From Jeremy: I wanted to ask you what you think are some of the biggest challenges facing adult common readers today. His answer is at the end. Some thoughts. Reviews. A lot of books get published and a lot of reviews. But most reviews are about the same books and are too long—and they give away the plot! I would like to see more composite reviews and more impressionistic ones. Notable that Goodreads is successful at this but most “Books” sections are not, noting that they do a very good job of what they set out to do.
